    Question wowza quicksync transcode video

    Hi there,

    I'm using QuickSync transcode in my workflow, it has a picture quality issue when i playback the output live stream. it would have a mosaic picture especially when scene changes or fast motion picture. when scene change happend, the picture will become blur and then it will turn into clear progressively.

    CPU: intel corel I7-3770
    Input: 8Mbps or 17Mbps 1080i/720i mpegts stream(mpeg2+ac3)
    (now transcode 3 input stream, cpu utilization percentage is 35%, GPU around 15%, memory take 8GB of 12GB)
    Transcode para:
    Any idea to slove this problem?

    Thanks very much!

    Do you see the same issue if you try using the default transcoding, as opposed to QuickSync transcoding?


    This will, at least, help eliminate a particular issue that Wowza Streaming Engine may be having with the source stream.

    Best regards,

    Hi, thanks for the reply

    The dufault transcoding is much better, i had making a copy of this two different output videos and shared in dropbox, you might check it


    you can find a obvious difference at the time 9th second.

    so any suggestions about this?
